Options:
1)shrimp tank but the water is a little turbulent (very high flow) (20g)
2)Ramshorn snail breeder tank. (10g) not sure that is a good idea either because I am always sticking my hand in there
3) Mystery snail + Apple snail tank. (10g) I think this is the best option.
4) Guppy tank haha
Any other thoughts and opinions?
